CARTON AND METHOD OF PACKING THE SAME.

Application filed December 3, 1923.

To all whom it may concern:

Be it known that I, CEsARE BARBLERI, a

' subject of the King of Italy, and a resident of the city of New York,in the county of New York and State of New York, have invented certainnew and useful Improvements in a Carton and Method of Packing the Same;and I do hereby declare that the following is a full, clear, and exactdescription of the same, referencebeing had to the accompanyingdrawings, and to the numerals of reference marked thereon, which formapart of this specification.

This invention relates to cartons and methods of packing the sameadapted more particularly to the packing of articles or other cartons ofnon-rectangular form in such a way that the latter cannot shake loose orbecome displaced in their containing carton during transportation.

While not restricted to such use, the invention is especially applicableto cartons adapted to hold smaller cartons of general triangularcross-section such as are employed for packing fiat triangular drinkingcu s.

Ilne of. the principal objects of the invention is the provision of acarton and method of packing the same adapted "for articles or othercartons of non-rectangular form.

Another object is the provision of a carton adapted to receive and holdsecurely smaller cartons of general triangular crosssection.

Other and further important objects of this inventionwill be apparentfrom the disclosures in the drawings and specification.

The invention (in a preferred form) is illustrated in the drawings andhereinafter I more fully described.

On the drawings:

Figure 1 is a perspective View of a carton embodying the presentimprovements.

Figure 2 is a plan view of the same after opemng.

Figure 3 is Fi re 1.

igure 4 is a perspective view of the upper end of one of the triangularcartons partially opened.

Figure 5 is a vertical section through one of the triangular cartons.

.As shown on the drawings:

The carton 1 is of common construction having sides 2, ends 3, flaps 4from the top a section on the line 2-2 of Serial No. 678,119.

each end of the carton 1. If these are not filled the cartons 6 would beapt to shake loose or become displaced. Consequently, triangular fillersare provided, such as 7,

which may conveniently be formed by folding a sheet of paste orcorrugated board into the desired shape.

It will be observed that the corners of the cartons 6 are'fiattened andas a result they can be packed in smaller compass than they could beotherwise.

Further the spaces left at the corners of the cartons 6 when they arepacked in the large carton 1 aid in the withdrawal of the cartons 6 asthe fingers may be inserted in such spaces.

This hexagonal or flattened corner form has several additionaladvantages over a truly triangular shape. In the first place the anglethrough which the pasteboard must be folded or bent is halved therebygiving .a stronger construction for the reason that the greater theangle of fold, the deeper the material must be scored to enable it tobend the required amount. Thus, while the wide sides of the carton 6'.make an angle of 60 with each other, the angles between the wide andnarrow sides are 120. Then where. the articles to be packed, although ofgeneral triangular form,'do not require a carton of exact triangularshape, considerable carton material is saved by flattening the corners.

A further advantage obtained by forming the sides of the cartons 6- ofequal size is that the same may be inserted into the outer carton 1without regard to the lateral disposition of said sides, as said cartons6 will interfit under any condition.

The ends of the cartons 6 are closed by overlapping flaps 8 and 9 asshown more particularly in Figure 4.

The cartons 6 are designed more particularly for holdin flat triangularpaper cups havin a folde bottom of greater thickness 51311 the top. Suchcups will, therefore, not stack evenly within the cartons 6. To provideuniform pressure upon the cups in spite of the inequality in thickness,fillers are arranged in the carton, preferably, as shown in Figure 5,both at top and bottom. These fillers may conveniently be formed of asingle piece of bent paste board, the body part 11 being of similarconfiguration to the cross-section of the carton and extendingthereacross while the flange portion 12 is arranged to engage the top orbottom flap of the carton and thereby hold the body portion at an angleto such end of the carton.

I am aware that numerous details of con? struction may be varied througha Wide range without departing from the principles of this invention,and I therefore do not purpose limiting the patent granted otherwisethan necessitated by the prior art.

I claim as my invention:

1. In combination, a rectangular exterior carton, and a plurality ofinterior cartons, each of the latter being of hexagonal crosssectionwith alternate sides of smaller width than the intervening sides, saidlarger and smaller sides being respectively 01 equal dimensions, wherebysaid cartons will interfit in the exterior carton under any manner oflateral disposition therein.

2. In combination, a rectangular exterior carton, and a plurality ofinterior cartons, each of the latter having a. cross-section of generaltriangular form with the apices of the triangle out 01f, said trianglebeing equilateral and its cut'otl' apiees being of equal width, wherebysaid cartons will interfit in the exterior carton under any manner oflateral disposition therein.

In testimony whereof I have hereunto subscribed my name.

CESARE BARBIERI.
